The area is mainly underlain by rhyolite, andesite, and tuff of the Jurassic Hazelton Group. The original interest on the property was in two approximately parallel, flat dipping quartz veins about 210 metres apart. They vary from about 0.9 to 1.8 metres in width. A number of other small quartz and quartz-carbonate veins are also present. Mineralization includes tetrahedrite, freibergite, native silver, galena, sphalerite, chalcopyrite, and pyrite. Ankerite is believed to be the dominant carbonate and tourmaline is present in small amounts.

Recently, attention has been focused on highly bleached and altered zones containing sulphide mineralization as disseminations and veinlets which surround the veins. Some samples have yielded relatively high gold and silver values. Petrographically the alteration consists of carbonate (dolomite), muscovite, quartz, plus or minus illite with minor pyrite and tourmaline.

Diamond drilling in 1990 intersected mineralized quartz- carbonate veins where one hole analysed 0.32 gram per tonne gold, 78.4 grams per tonne silver, 0.19 per cent copper, 5.7 per cent lead and 2.7 per cent zinc over 0.2 metre of core (Assessment Report 20948, page 6).
